The ways that the irrigation changed yuma was that the lands were very extremely fertile and productive and capable of enormous crops.The 80 percent of water that we had would go to agriculture. Giving away land will harm the economy in foods,security,and etc.The model of efficiency was to try and save water in dams so we would have not lost too much. They gave up to 2.8 billion into the yuma economy. The water diverted to other farms so the water decreased its percent since 1990. To progress they tried making dams that can hold at least 22 inches of water.So irrigation changed yuma because we were no longer losing too much water we had better fields better crops and better efficiency. The people that were in yuma at the time maybe were mad because they were losing too much water and the crops would flood so that is why they started making dams as deep as they can so they stored the water and they stopped losing the amount of water they were losing.It helped yuma by a lot because we hardly get rain here we get more like dust.
Irrigation took a big place in this situation because they were losing crops or they would get too much water and then die out later on.
